Skip-Counting

Skip-counting is a strategy used to count by a certain number, or to count by multiples. It is often used as a way to introduce multiplication, as skip-counting by 2s, 3s, 4s, etc. can be thought of as finding the product of the number being skipped and the number of times it is being skipped. For example, to skip-count by 3s from 0 to 12, one would say or write 0, 3, 6, 9, 12. Other examples of skip-counting are finding common denominators, so that addition and subtraction can be performed, or counting in binary.
